Blockchains and Decentralisation for Valuable Personal Data
The over centralisation of data has led Tim Berners-Lee to call the Web 'anti-human'. This PhD will investigate how a combination of blockchain and decentralised data technologies (e.g. Solid) can be used to give users control of their own data whilst ensuring that others can still trust its contents, where it might otherwise be valuable to users to edit it. Educational qualifications are one example of this, but there are many others. This PhD will build on existing work where we have created a framework (LinkChains) for handling personal and sensitive data which combines decentralised data platforms with blockchain-based verification.

Blockchains for Trustworthy Collaborative Agents
Collaborative adaptation opportunistically composes the capabilities of multiple agents in unforeseen conditions to satisfy given requirements. However, this approach assumes that individual components will always behave as expected. This PhD project will investigate how to represent and reason about the capabilities of agents in a verified trustworthy fashion. This will include speculating and reasoning about their potential and recorded misbehaviour, and dynamically composing them in order to continue to satisfy requirements. The aim is to enable verifiably trustworthy collaboration in complex situations even when some agents fail or are malicious.

Area 2. Computational Social Science
AI and Digital Normativity
To highlight useful trends and patterns, Artificial Intelligence (AI) technologies exploit norms. However, when applied to data about humans, this creates additional risks for communities that do not conform to societal norms, including those who are already marginalised. This PhD project will explore this very timely and important concern for the field of Ethical AI, in particular as AI for Social Good (and equivalents) have emerged to ensure that AI technology is applied to society's most pressing problems. The candidate will develop novel approaches for understanding digital normativity and its impacts, using a combinational of computational and social science methods.

Recommender Systems and the spread of online harm
Recommender Systems have been pointed out as one of the major culprits of spreading online harm (misinformation, radical content, polarization) in the digital sphere. They are accused of promoting the creation of filter bubbles, lowering the diversity of information users are exposed to and the social contacts they create. This PhD will explore which particular types of recommender algorithms are more prone to recommend and spread harmful content, and if, and how, existing recommendation algorithms and evaluation metrics, can be modified or adapted to mitigate this spreading effect. This project will be conducted in collaboration with Universidad Autonoma de Madrid (UAM).

Supporting Scientific Research with Knowledge Graphs
This PhD project aims at developing a new generation of intelligent systems for exploring and analysing the scientific literature with the goal of improving efficiency and verifiability of research. The traditional document-centric approaches for searching the literature do not scale to the large number of articles produced today. We aim to introduce a modern knowledge-centric solution by automatically extracting structured representations of research knowledge from very large repositories of research publications. The candidate will design novel approaches that exploit these knowledge graphs for answering complex queries on the literature, recommending articles, predicting emerging topics, and producing research hypotheses.

Area 4. New Media in Society
New Media and Society research aims at going beyond the study of Computing and ICT from a technology perspective, and looks at improving our understating human values and the impact of technology innovations on people's lives and their communities. This research particularly looks at ways to use new media to promote social justice and tackle complex societal challenges of inclusion and disadvantage.
Artificial Intelligence Systems for News Analysis and Media Agenda Monitoring
This project aims to design novel AI techniques for multi-dimensional understanding and analysis of news. To this purpose, the candidate will develop novel approaches that will combine machine learning and natural language processing techniques for extracting a comprehensive semantic description of news content to support journalistic competence. The resulting knowledge graphs will enable the representation and reasoning over news frames to perform comparative analyses of media outlets, including viewpoints and biases. The candidate will focus on tasks such as news classification, prediction of news topics, monitoring event coverage, and agenda-setting analysis.

Bias in AI models
Advanced Artificial Intelligence (AI) models are used widely in the Financial Services Industry to make automated consumer decisions. Whilst the exercise typically follows a strict governance & ethical conduct, such models might still contain, or be likely to develop in iteration, hidden proxies or patterns related to protected consumer categories such as age ethnicity, disability, or religion, thus injecting undesired and undetected bias in their decisions. This PhD will investigate the use of data science methods for the automatic detection and removal of such patterns in AI applications used in the Financial Services Industry. The project will be performed in close collaboration with the Data Science Lab team from Visa Europe in London.

Improving Citizen Participation in the Climate Debate with Multimedia Deliberation Technologies
The public is increasingly worried about climate change, especially young generations are concerned about their future on this planet and seek new ways to be engaged in a more democratic inclusive discussion about climate action. Still, technology for citizen engagement and online deliberation of climate change issues are either very simple (such as social media) but inappropriate to support heathy and effective deliberation, or too complex (such as as Kialo, Deliberatorium, DebateGraph, The Evidence Hub), and therefore, hardly inclusive and adopted at scale. This PhD research aims at improving accessibility of large-scale online discussion platforms by providing novel features for voice-to-text translation and multimedia contribution to the online debate (in form of audio and video file). This will enable participants to use oral and gestural communication to engage with climate debates, thus promoting participation from younger and/or less digitally savvy communities (which usually are less at ease with written communication).

Novel Technology to Support Social Activism
This project aims to design novel technologies, including ubiquitous and social media, to support activism and social justice towards some Sustainable Development Goals (SDGs). The candidate will work in between social sciences and technology design and development, conducting user-centred activities such as interviews, workshops and participatory design sections. It is also expected that the candidate will engage with local communities, charity organisations and schools and will pilot technical solutions using sensors and social media.

Real-Time Multimedia Interaction Technologies to Reduce Social Polarisation
Political instability and conflict plague the world. Peace building education is becoming more than a call, it is a paramount civic skill that any 21st century citizen should learn to practice. Still, there is a growing distrust toward our human capability to 'change our mind', and develop social empathy toward people that we perceive as "different from us". This PhD research focuses on multimedia narrative interaction technologies as means for people to reflect, think critically and challenge personal bias. Building on our research on Democratic Reflection the successful candidate will improve and test the capability of this technology to promote critical thinking and reduce polarization of opinions in highly dividing contexts (such as post-war or political unrest scenarios). Changing assumptions is a crucial skill to promote social tolerance and build peace in our divided society, this PhD will investigate the theories, methods and tools to enable it.

Tools for discussion and collaboration in distance learning
While asynchronous approaches to distance learning in higher education support flexible forms of study, they can limit the level of student's interaction with other students and their lecturers. This project will develop and evaluate the use of synchronous (i.e. real time) approaches to promote active learning through discussion and collaboration as part of a blended approach to distance learning. This is likely to involve the integration of communication technologies (e.g. web conferencing, web broadcasting, instant messaging and online polling) with collaborative learning and teaching strategies (e.g. team-based learning, think-pair-share, problem-based learning, peer teaching, peer assessment).
